The publication by the International Renewable Energy Agency (IRENA) outlines the latest landscape of innovations that can accelerate sustainable development based on renewable energy, emphasising that the transformation of energy systems requires a combination of technological advances, policy changes, market design, and business models.

The report identifies 40 innovations which, when strategically combined, can help build more resilient electricity systems, expand access to energy, and promote inclusive local development. It is presented as a guide for policymakers and regulators to design solutions adapted to national and local contexts, aiming to go beyond the mere deployment of technologies to address social and economic barriers in the energy transition.

Although the report has a broad focus on energy systems, several of the proposed innovations and principles are directly relevant to building sustainability. It promotes renewable electrification of energy demand, where more efficient buildings with greater integration of renewables can reduce their carbon footprint and reliance on fossil fuels. This includes the adoption of decentralised solutions such as building-integrated photovoltaic systems, digitalisation to optimise energy efficiency in real time, and energy management models that allow buildings themselves to act as active elements of the grid.

The convergence of renewables with improvements in building efficiency, design, and operation not only helps reduce emissions but also strengthens system flexibility and improves overall energy balance.
